How to use test_should_get_multiple_cookies method in Playwright Python

First of all, Playwright already has a full suite of selectors that work on the live page, so to eliminate a dependency, speed up your scrape, use less code and avoid weird errors when the static HTML snapshot gets out of sync with the live page, I suggest skipping BS.

On to the main problem, you've done good by printing the HTML to see what sort of response you're dealing with. The 404 page indicates you've been detected as a bot when running headlessly, but this can often manifest as a captcha, Cloudflare browser check page, or other "are you a robot?" notice.

As with everything in scraping, there's no one-size-fits-all solution, but one typical approach is to set a custom user agent string:

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch(headless=True)
    ua = (
        "Mozilla/5.0 (Windows NT 10.0; Win64; x64) "
        "AppleWebKit/537.36 (KHTML, like Gecko) "
        "Chrome/69.0.3497.100 Safari/537.36"
    )
    url = (
        "https://www.apple.com/br/shop/product/MV7N2BE/A/airpods-com-estojo-de-recarga"
    )
    page = browser.new_page(user_agent=ua)
    page.goto(url, wait_until="domcontentloaded")
    sel = "span.as-price-installments:last-child"
    text = (
        page.wait_for_selector(sel)
        .text_content()
        .replace("à vista (10% de desconto)", "")
        .strip()
    )
    print(text)  # => R$ 1.399,50
    browser.close()

Chrome can't launch itself with a User Profile folder, it must launch from a User Data folder. If you want a specific profile, you can set a profile as your default Chrome profile and then copy the new User Data folder elsewhere for your application (or use original User Data folder).

There is no outer_html out of the box. But it's not hard to implement it:

locator.evaluate("el => el.outerHTML") 

Your glob patter for the url is incorrect, should be something like this:

 page.wait_for_url('**/order-received/**')

To get the id you will need the parent, and evaluate the id attribute

const td = page.locator("text=Edição 993 link direto gdb");
const tr = await td.$('xpath=..')
const id = await tr.evaluate(node => node.getAttribute('id'))

The only way I found is wrap the goto inside a try-except block

Content of main.py

from playwright.sync_api import Playwright, sync_playwright, expect

with sync_playwright() as p:
    #We define the browser, the context and the page
    browser = p.chromium.launch(headless=False)
    context = browser.new_context()
    page = browser.new_page()
    with page.expect_download() as download_info:
        #If we navigate without try, it will throw an exception and it will stop our script, so, we wrap it inside a try except block
        try:
            page.goto("https://manueltgomes.com/wp-content/uploads/2021/09/ParseHTMLLInks_1_0_0_1.zip")
        except:
            pass
    download = download_info.value
    download.save_as(f"./{download.suggested_filename}")
    context.close()
    browser.close()

Then just run python3 main.py

The file will be saved in the same path of the main.py file

At the end of each iteration of "y" you issue a mouse up event. However, you dont issue a mouse move event to the start of the new line before putting the mouse down again.

Try the below code:

    for y in range(100, 1000, 100):
        # Generate mouse points
        points = []
        wm(start_point, y, x, y, M_0=15, D_0=12, move_mouse=lambda x, y: points.append([x, y]))

        page.mouse.up()
        # Move mouse to start of new line
        page.mouse.move(points[0][0], points[0][1])
        # Mouse back down
        page.mouse.down()
        #Iterate the remaining points
        for point in points[1:]:
            page.mouse.move(point[0], point[1])
        page.mouse.up()

It's been suggested by the developers of scrapy_playwright to instantiate the DOWNLOAD_HANDLERS and TWISTER_REACTOR into your script.

A similar comment is provided here

Here's a working script implementing just this:

import scrapy
from scrapy_playwright.page import PageCoroutine
from scrapy.crawler import CrawlerProcess

class ProductSpider(scrapy.Spider):
    name = 'product'

    def start_requests(self):
        yield scrapy.Request(
            'https://shoppable-campaign-demo.netlify.app/#/',
            callback = self.parse,
            meta={
                'playwright': True,
                'playwright_include_page': True,
                'playwright_page_coroutines': [
                    PageCoroutine("wait_for_selector", "div#productListing"),
                ]
            }
        )

    async def parse(self, response):
        container = response.xpath("(//div[@class='col-md-6'])[1]")
        for items in container:
            yield {
                'products':items.xpath("(//h3[@class='card-title'])[1]//text()").get()
            }
        # parses content

if __name__ == "__main__":
    process = CrawlerProcess(
        settings={
            "TWISTED_REACTOR": "twisted.internet.asyncioreactor.AsyncioSelectorReactor",
            "DOWNLOAD_HANDLERS": {
                "https": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
                "http": "scrapy_playwright.handler.ScrapyPlaywrightDownloadHandler",
            },
            "CONCURRENT_REQUESTS": 32,
            "FEED_URI":'Products.jl',
            "FEED_FORMAT":'jsonlines',
        }
    )
    process.crawl(ProductSpider)
    process.start()

And we get the following output:

{'products': 'Oxford Loafers'}

Just in case you had the same query or were struggling with dynamic web scraping. You have to use CPython and install a webscraper such as Playwright or BS + Selenium

I used playwright which is far more straightforward and has a very much appreciated inner_html() function which reads straight into the dynamic flex HTML code. Here is the code for reference.

#part of the help to write the script I got from https://stackoverflow.com/questions/64303326/using-playwright-for-python-how-do-i-select-or-find-an-element

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch(slow_mo=1000)

    page = browser.new_page()
    page.goto('https://vemcount.app/embed/widget/uOCRuLPangWo5fT')
    central = page.query_selector("p.w-full span");
    print({'central': central.inner_html()})
        
    browser.close()
 

Afterwards I am trying to run the .py script remotely from Grasshopper through a batch file and read the output through a txt or CSV file from within Grasshopper.

If there is a better way I am more than happy to hear your suggestions.

Yours,

A Beginner in Python. :)
